[SOLVED] New build froze watching netflix with repeating audio.

Solution
Built a PC for my cousin last week, he said it froze with rapidly repeating audio whilst watching Netflix, this is the first time it happened. He said he had to reboot the PC. What could have caused this?

Netflix could be the cause. Its not always the PCs fault that a program crashes. If it doesnt happen again, theres no reason to worry anyway. Its most likely just a glitch. Everyone gets them once in a while.
